Frequently asked questions
Is Mistral Large 4 as good as o1?
Mistral Large 4 is open-weight and competitive on many tasks, but o1 may still lead on the hardest reasoning and agentic work. The gap keeps narrowing — benchmark both on your actual use case before deciding.
Can I run Mistral Large 4 locally?
Yes. Mistral Large 4 has open weights, so you can self-host it on your own GPUs or run it via a low-cost API. o1 is API-only and cannot be self-hosted.
How much cheaper is Mistral Large 4?
Mistral Large 4 costs $4.18/M output vs $60/M for o1 — roughly 14x cheaper via API, and free if you self-host.
o1 vs Mistral Large 4 — which should I pick in 2026?
Choose Mistral Large 4 if you want to self-host, keep your data private and skip per-token fees — it's open-weight and runs on your own hardware. Choose o1 if you want frontier capability through a managed API with zero infrastructure to run.
